Prototype 7

Rayner went home. The next morning he could not remember anything that had happened because when he got home he crashed into a shelf. That day, at night, he was intrigued by what had happened, so he went for a stroll to refresh memory. He was going down the street when he heard a terrifying music, and out of nowhere a man appeared begging, demanding money, and as Rayner said he had no money, the beggar pulled a knife, stabbed him in the belly and left Rayner lying on the street, with a puddle of blood beneath him… but someone was coming in the distance… Who?
